The thermal regulation function of clothing can additionally assist the human body in thermal management in low temperature environment.Based on the two-way memory effect,the design and performance testing of shape memory alloys are carried out.The deformation height of the shape memory alloy at different temperatures is determined and a spring quantity scheme is designed to explore the insulation rate and thermal resistance changes of the fabric system under the permutation and combination of height and number of spring.The results show that both the height and the number of springs have an impact on the thermal insulation performance,and the thermal insulation and temperature adjustment effect of the fabric system is the best when the number of springs is 7.
